10 Claims. (Cl. 229-62) This invention relates to closure means particularly adapted for closing the open ends of containers such as bags and the like.

An object of this invention is to provide improved closure means for closing the open end of flexible walled containers such as bags or the like, the construction of the closure means being such as to allow repeated opening and closure of the container to which the same is applied.

Another object of this invention is to provide bag clo sure means of the character described, which is readily manipulated to effect the rapid opening or closing of a container to which thesame is applied.

A further object of this invention is to provide an improved bag closure means which is adapted to tightly grip the open end portion of a bag, allowing the bag to be suspended by the closure means without slippage of the bag relative to the closure means due to the weight of the bag contents, yet allowing easy removal of the closure from the bag and repeated re-use of said closure to reclose the bag.

Still another object of this invention is to provide improved bag closure means having a structure allowing rapid application thereof to the mouth of a bag to close the same and permitting the closure to be opened by simple manipulation to gain access to the contentsof the bag. 7 Yet a further object 'of this invention is to provide improved bag closure means usable with flexible walled bags of transparent or opaque material, the closure means being of a construction which aids 'in maintaining the shape of the bag and afiords means for effectively disposing the bags on shelves or the like.

Yet another object of this invention is to provide improved, reusable bag closure means adapted to carry various indicia, markings and the like, for the purpose of clearly indicating the contents of the bag, sizes, weights and thelike, as well as trademarks or other identifying insignia or markings:

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

Fig. 11 is a plan view of a modified form of the invention, in opened up blank form; Fig. '12 is a plan view of the closure shown in Fig. 11, applied to a bag container; and

With the increased use of flexible walled containers, particularly bags made from cellophane, polyethylene, vinyl or epoxy resins, in both transparent and opaque forms, it is vital that the closure means used on'such bags augment and enhance the utility of the bags. Thus, with a re-usable closure, the contents of the bag may be withdrawn for inspection or the like after opening such a closure; returned to the bag which is then reclosed, thereby preserving the contents from soilage or the like.

As shown in the drawings, the bag closure embodying the invention comprises a blank, indicated in Fig. l, which may be formed of cardboard, stiffened paper, plastic sheeting, wood veneer or other materials having suitable stiffness allowing the same to retain a shape and to be scored or creased to provide panels andtabs as elements of the closure.

The closure comprises a rectangular panel 8 with succession of narrow folding panels 3, 2'and 1 extending from the top edge thereof; panels 3, 2 and 1 being defined by parallel crease lines-d, c and b upon which said panels may be folded. The width of folding panel 1 is sub stantially equal to that of panel 2as measured from edge a of panel 1 to crease 'line b and from crease line b to crease line 0. v a

' A pair of shallow tongues or projections 9 extend from the edge a of panel 1, being longitudinally spaced andhaving a depth measured to line ee. 0n crease line c is formed a pair of slots 10 aligned with tongues 9 and adapted to receive the same, as later described.

A other resin sheeting, fabric and the like.

The closurefurther includes elongated tabs 4, 4 extending respectively from the opposite ends of panel'8,

with intervening narrow fold panels 5 formed by creasing or scoring. The width of panels 5 is substantially equal to that of panel 3. The tab 4 is formed with a tongue 7 at the outer end thereof which is receivable in slot 6 formed in tab 4'.

The closure of the instant invention may be associated with bags ofvarious shapes, forms and dimensions; formed from paper, cellophane, polyethylene, vinyl or As'shown in FigsJZ, 6, the open end of the container is disposed over theinner surfaces of panels 8, 3 and 2, the panel 1 is folded downwardly on crease line b toward panel 2 and tongues 9 are pressed against linear portions of the container walls, displacing the same out of their plane and forcing the same through slots 10, as shown in Figs. 3 and 7. Thus, the marginal portion of the container is locked between panels 1 and 2 and securely anchored in place by tongues 9 received in slots 10.

The panels 1, 2 are further folded on crease line 0 towards panel 8, as shown in Figs. 4 and 8; and tabs 4, 4 are folded toward each other and interengaged through tongue 7 received in slot 6 of tab 4', thus maintaining the panels 2, lfrom unfolding Narrow panels t 3, 5 provide thickness forthe closure, to allow the contents of the containerto extend into close proximity to the' mouth thereof and to be disposed between panels 8 and sure panel 8, then panels 3 and Smay be omitted, and folded panels 1, 2 will lie close to panel 8 with the interlocked and positively anchored bag end secured therebetween: s 1

It is further understood that the tongues 9 varied in number and longitudinal disposition, as jwell as longitudinal dimension, in accordance with the natureof the material from-:wh-ichthecontainer is formed, to insure proper anchorage in slots 10 without tearipg. of the container material. a

Panels 8, 2, 3 and 5 afford on their outer surfaces means for'imprinting thereon indicia and markings of all kinds to show sizes, weights, source of manufacture, trademarks, ornamental matter and the like. Furthermore, the closure le'nds shape to the containe'r and the contents thereof. The bag container with the closure of the instant invention lendsitself to storage on shelves with'the closure extending forwardly and panel 3 thereof visible to display the markings thereon.

A; modified form of closure is shown in Figs; 11 and 12, wherein the slots 10' are replaced by slits 10a formed in the-crease line short cross slits 11 being formed in panel 8- at the opposite ends of slits 10a, to provide short, bendable tabs 12 which are engageable by tongues 9 when panel 1- isfolded' on crease line b toward panel 2. Thus, the tabs 12 are bent outwardly by tongues9 to become interengaged therewith, taking with the tongues linear portions of the bag material for positively anchoring the same, as previously described.

Also, end tabs 4, 4' may be replaced by wing shaped members 13, 13' foldable toward each other and toward panel'8 on crease lines 14. The members 13, 13' include tabs 15 extending laterally outward of the lower portions thereof and arm portions 16 extending laterally outward of the upper portions thereof, said portions 16 being longer than tabs 15'and extending parallel thereto. Panel 2 is formed on the central portion thereof with a. pair of transverse slots 17.

As shown in Fig. 12, after the mouth portion of the bag container has been interlocked between panels 1, 2 and anchored in place by tongues 9 and interengaging tabs 12, the members 13, 13' are folded toward each other and in superposed relation, tabs 15 being inserted in slots 17, to retain folded panels 1, 2 against panel 8 and to dispose arm portions 16 in a manner to provide handle means, leaving a space18 to receive the fingers when overlapping arm portions 16 are grasped to carry the bag container and the contents thereof.
